Dynamically setting ImagePath from absolute path in WinRT

I am trying to create a GridView of dynamically-created Grid items, each of which have their background set as follows:

<Grid.Background>
     <ImageBrush ImageSource="{Binding FilePath}" Stretch="UniformToFill" />
</Grid.Background>

If FilePath is the absolute path to the file that should be loaded for each Grid item, is there a way that I can convert this value to an ImagePath so that the image will load?

I am getting the FilePath using a file picker. The value is then being saved to an ObservableCollection that is loaded when the app starts and displayed by being set as the DataContext.

Solution

  • There is no ImagePath property that I know of and ImageSource is not a path or even a Uri. You should probably bind your ImageSource to a BitmapImage. Simply create a new BitmapImage and call SetSource or SetSourceAsync if you want to wait for it to load before updating your image - e.g. to show a placeholder image, a progress indicator or fade in the image.
